MACHINE FOR SWAGING BEVELS.

SPECIFICATION forming part of Letters Patent No. 330,520, dated November1'7, 1885. .a

Application filed September 23, 18B5. Serial No. 177,907. (No model.)

To all whom it may concern:

Be it known that I, JOE T. SP1-3ER, of Pittsburg. in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Machines for Swaging Bevels; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to an improvement in` machines for swaging bevels.

'The object is to provide a machine of simple construction capable ofswaging a bevel of any desired length or angle on any shaped piece ofiron or steel. Y.

W'ith this end lin view my invention consists in certain features of.construction and combinations of parts, as will be hereinafterdescribed, and pointed out in the claims.

In the accompanying drawings, Figure l is a view of the machine in sideelevation. Fig.

2 is a front view, and Fig. 3 is a plan view.

A represents the base or support vfor the lower die, the roll, and thegear for running and truing the upper dies. The die-block B is set in arecess, b, formed in the front portion of the support, and is adapted tobe elevated or lowered by means of a wedge, C, which is insertedtransversely to the support A, and resting on an inclined seat, c. Theupper face of the block B is provided with a channel or recess, d,extending lengthwise of the base A, in which channel or recess the lowerdie, D, is adapted to rest and have a sliding adjustment. Journaled inthe support A, above the die D, is the roller E, provided on its facewith recesses or sockets adapted to receive and retain the upper dies,e, in the proper positions to engage the piece of iron or steel to belaid on the die D. The faces of the dies e are beveled in the directionof the axis of the roller E, or they may be made parallel with theroller, for the purpose of gradually reducing the piece operated upon. Frepresents an emery-wheel or other form of grinding-wheel, secured on ashaft, f, the latter having the same general direction as the beveledface of the die e nearest thereto, thus placing the face of theemery-wheel squarely against the beveled face of each of the dies e asthey are brought in succession to ment in a direction transversely tothe shaft, either by bolts working in elongated slots h or otherordinary devices, by means of which the face ofthe emery-wheel may beset at different angles tothe faces of the dies e, and thereby cut themdown to different angles of bevel. ment in the direction of the axiseither by a sliding frame, or other approved means for the purpose .ofrunning it across the faces of the dies e. .Y By means of theemery-wheel the faces of the dies are kept squared up in a condition toform a true bevel on the piece resting upon the lower die, upon whichthey successively act. VThe emery-wheel F is conveniently driven bymeans of a friction or band pulley, g, in engagement with a frictiondrive- Wheel or connected with a drive band-pulley.

(Not shown.) The main shaft is driven by the engine or other powerthrough suitable transmitting mechanism, and by means of suitable gears,G G', imparts motion to the roller E.

By moving the die D, with the piece to be beveled resting thereon,forwardly and backwardly beneath the dies e, by elevating the die D bythe wedge beneath the die-block B, and by keeping the faces of the diese the desired bevel and true, the work may be reduced to an edge by agradual elongation with great exactness and any desired angle of bevel,no matter what the shape of the work to be beveled may be.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespirit and scope of my invention; hence I do not wish to limit myselfstrictly to the construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. The combination, with a verticallyadinstable lower die, of a seriesof bevel-faced dies rigidly secured in the rim of a roller, and adaptedto engage work laid on the lower anvil and reduce the same to an edge bygradual elongation, substantially as set forth.

2. rIhe combination, with a vertically and horizontally adjustable lowerdie, of a series The wheel Fis also capable of adj ust-` ICO ofbevel-faced upper dies secured in the face of a roller, and adapted toengage successively a piece of work resting on the lower die,substantially as set forth.

3. The combination, with a lower die and an upper die secured in theface of a roller, of a grinding-wh eel adapted to engage the face of theupper die as the roller revolves, and thereby keep the face true,substantially as set forth. i

4. The combination, with a lower die and a series of dies secured in theface of a roller, of au emery-wheel adapted to form a true bevel on thefaces of the several dies, substantially as set forth. y

5. The combination, with a lower die and av series of dies secured inthe face of a roller, of

an emery-wheel journaled in longitudinal adjustment in bearings having alateral adj ust` ment, for the purpose substantially as set forth.

Y 6. The combination, with the die block adapted to be verticallyadjusted by a wedge, and the lower die having a horizontal adjust- Imentin the die-block, of a series of upper
